Essay Sample on Screen Brightness of Cellular Devices and Radiation

Introduction

According to Summerville, 2017), radiation is a process through which energy is given off from particles in the form of a wave. The emission of these waves results in an ability to ionize different molecules that means that it can cause a molecule to either gain or lose an electron. Most times if a molecule gains or loses an electron then there results to a molecular imbalance which leads to division of cells rapidly and cancer. He further states that there has been researching conducted although not convincing and conclusive enough done on the same and has been released through the media.

Miakotko, 2017, explains that smartphones are a new invention to human beings that have affected human beings significantly especially because they have become a significant part of the lives of human beings. The various uses of the smartphone include using them for pictures, videos, personal information and other essential data in the normal carrying out of their businesses. The smartphones are enabled with computing abilities that help users, for example, to access the internet using their phones with ease. He explains that despite these advantages, the people are not aware of the disadvantages that are caused by the same among them being electromagnetic waves that affect the human brains, back and neck extremities that are most times generated by the devices that are hand-held by people.

What Causes Screen Brightness?

The prevent blindness website, 2017, has defined digital devices and gives the examples as computer screens, smartphones, tablets and other devices in the same category. The site describes the various reasons why the yes may be at risk for being damaged especially with the light emitted from the digital devices. It has been explained that these devices give off radiations in the form of ultraviolet rays. However, the quantity of the radiation given off is minimal. It has been described that the light is not in the levels that can cause damage to the eyes for example cataracts. The time spent looking at the blue light emitted from these devices is also a concern because people spend a lot of time on the machines and say that it is the light whereas it is the long period spent looking on the television. It has also been found out that the eyes of children absorb more of the blue light than those of adults.

Krishnan, Zakaria, Khalil and Jofree, 2016, explain that nowadays electronic devices are used widely and are seen as those things which are very important because they help them conduct their daily duties. However, every good idea does not lack a setback which in our case is the emission of radiations which are very serious and cause serious harm to the body of the human being. Technology influences all the operation of these machines and people only see the right side. With the reactions of these machines, the effect produced in our bodies is dangerous to the extent that the lives of the people using the devices are at risk while they still are not aware. The research conducted was to help people to be educated on the dangers of the electronics being used.

The Eye Health Medical Reference, 2019, has an article of how computers affect the vision of a person. There is an explanation of a condition known as Computer Vision Syndrome which is a condition caused by the use of computers. The state includes eye strain and pain, and from research, a percentage of people working at a computer have some symptoms of the syndrome. The condition occurs when the eyes follow the same path time and again. The more a person continues with the movement, the condition can get worse. To avoid this, when working using a computer, the eyes should be focused at all times. Changing images on the screen reacts with the eyes, therefore, the brain can process what it sees. The jobs require a significant contribution of effort from the muscles of the eyes. If a person already has an existing problem with their eyes and use a wrong prescription or do not use glasses when they are supposed to are likely to suffer more.

According to research by Krazycos, 2018, she uses a story of a person who has been working on her computer for five hours and then noticed that her eyes felt dry and that they started to burn. Then the person explains that her vision became blurry like she was going through a haze. The persona knew what was going on. It was a digital eye strain which is also known as Computer Vision Syndrome. More people continue to suffer from the condition the more time they spend on a computer, tablet, , and other digital devices. Hinkley s spokeswoman for American Optometric Association says that it should be fast that as people move towards smaller devices, which is where the use of these devices also increases or levels up in our daily lives. A population of almost 70% of adults in the United States explains that they have received the symptoms of digital eye strain. Care providers have proven that those working for long hours on devices looking at the screens 60% of them suffer from this condition. As children continue to acquire cellphones at an early age, the problem has now extended even to the kids in a way that has not been experienced before.

Bahl, 2018,) in his article explains that the blue light on the phone is maybe permanently causing damage to the eyes. He argues that spending too much time on the screen can wreck a person's eyes. The phones, laptops and other devices have the light which Bahl claims is toxic for our eyes. He explains that scientist from the University of Toledo may have found out that the blue light given off from the devices has a potential degeneration of macular that results to loss of vision in a country like the United States. The Blue light from the devices harms our eyes by damaging the retina of the eye says the assistant professor at the University of Toledo chemistry department. Macular degeneration results from photoreceptor death in the retina. The function of photoreceptor cells is to capture visual images and then send a signal to the brain using the retinal molecule. Retinal is produced in the eye is triggered by blue light and then causes different chemical reactions which are later poisonous to the eye. They claim that the most affected group is above age 60. However, with more technology, it will continue to increase even on the younger persons, the more the blue light is ordinary.

Tipper, 2017, also explains the blue light which he terms as "blue screen of death." He relies on research conducted by Koreans who claim that the low-intensity light that is produced by our laptops and smartphones is a contributing factor leading to the damage of the cells of the eye. With their research, they believe that there could be an aid to deal with this challenge by producing devices that are less harmful to our eyes. The blue light especially from a shorter wavelength can damage the cells in the retina just as Bahl had stated in his research. An explanation of how the shorter wavelength affects the eye has been included in the article that when the wavelength is short, the light doubles the death rate in human retinal cells compared with the cells kept in the dark. There is also another molecule N-retinylidene-N-retinylethanolamine which reacts with light to produce radicals to human retinal cells and exposes them to different light wavelengths. These lights affect the eyes with different intensity with the blue light having the highest rate.

How to Reduce Radiation Effect

Despite the challenge that has resulted from the use of computers and tablets and other digital devices especially with the eyes, some researchers have found ways through which a person can protect themselves from the challenge. Shandrow, 2014, gives some tips on how to save the eyes from the pain that is experienced especially after using a smartphone. The first one she says that a person should blink not once or twice but many times she explains that flashing many times will help to keep the eyes moist thus will not suffer from dry eyes. The second one is to minimize glaring she encourages using a matte glass protector to reduce the light from the phone. The third is to take breaks from the phone she explains of a 20-20-20 rule which means for every 20 minutes spent looking at the phone the 20 seconds should be spent looking at an object that is 20 feet away. Fourth is to adjust the light to minimum brightness that should not strain the eyes. The text size in the phone and contrast should also be improved to avoid straining the eyes. Finally, she explains that the phone should not be held closer to the eyes.

Research also conducted by Christian, 2017, explains how a person can reduce exposure to light from a computer. A person should not be on Wi-Fi all the time because Wi-Fi emits harmful radiation. The laptop should not be used while on the lap especially if connected to Wi-Fi there is a shield for EMF radiation on the computer. A person should be careful on magnetic field exposure which prevents field radiation. A person should take breaks from the computer to stay safe. There are plants like cacti and aloe-vera that are proven to absorb EMF radiation so a person should get them. A person should always aim at avoiding wireless accessories that emit some frequency which is harmful. It is also essential that a person eats healthy to be protected from EMF radiation. Limit the exposure to the devices is the most simple and common thing to do to avoid radiation.

Burrell, 2010, who Christian borrows significantly from explains the methods that a person can use to be safe from all the harmful effects that emanate from using the wireless and new gadgets that have been introduced to us by technology. The way out, as explained by Burerll, is not any different from the discussion with Christian above apart from the aspect of using a Himalayan lampstand made of salt. The lampstand releases negative ions while electrical devices release positive ions, therefore, help to cancel the electromagnetic radiation from the electrical devices which still is an advantage to avoid the challenge of positive ions in the environment to maintain ionic balance.

Heiting and Wan, 2018, have also provided practical ways through which a person can stop further damage of the eye to avoid critical results that may arise as a result of working throughout on the computer. An example of the method that they give is to go for a check-up the moment a person realizes that they are experiencing different changes on the eyes. Using a room that is well lit, the display should be upgraded to enhance proper vision and also adjust the computer setting to a method that is favorable and also to prevent glaring and blinking more often. These methods will help people be in a convenient position to deal with the challenges of radiation affecting them in their daily activities.
